Nighttime view of tephra-jet explosion, Kīlauea, Hawai‘i
Incandescent arcs trace the path of lava fragments cast out during a tephra-jet explosion at the Waikupanaha ocean entry in 2008. This is a relatively small explosion, reaching a few tens of meters (yards) height, while one earlier in the day was nearly 70 meters (230 ft) in height.

Fissure 8 continues to send lava to the sea
The early morning helicopter overflight of the lower East Rift Zone shows lava continuing to enter the sea at Ahalanui. The southern margin of the flow remains about a quarter mile from the boat ramp at Isaac Hale Park (jetty visible in the center left of the photo). View to the northeast.

Longear sunfish (Lepomis megalotis)
The longear sunfish is a freshwater fish in the sunfish family. An increase in sunfish in southeastern streams, intentionally stocked or unintentionally transplanted, has caused the composition of fish species among streams in the Southeast to become more similar. Such homogenization of species is an emerging and pervasive threat to biodiversity.

2008 Donghekou Landslide
Photograph of the Donghekou Landslide, triggered by the 2008 Wenchuan, China Earthquake. This landslide had 3 sources areas: the mountain slope at the top right of the photograph a second area primarily resulting in a rockslide that occurred to the left of the scientists, and one to the right, across the river (not shown in picture).
